Al Gore
When it came to the public life of American politician Al Gore, the unexpected truth about the man who was the subject of the 2006 Academy Award-winning documentary "An Inconvenient Truth" was that the movie -- which came well after his years of dedication to American politics -- did more for the stiff and sometimes unappealing politician than decades of public service could. The documentary paved the way to his crowning achievement, the one most elected leaders simply dream about, a Nobel Peace Prize.
